open-iov.git/tools/guest-diag/cuda_cycle.sh, branch cs-share Open-IOV vGPU-IO: host-side GSP emulation for unmodified NVIDIA guest drivers https://git.vgpu.io/open-iov.git/atom?h=cs-share 2026-09-29T13:51:22+00:00 tools: cuda_cycle.sh - detect channels from dmesg (client timeout is ~30 s) 2026-09-29T13:51:22+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-09-29T13:51:22+00:00 urn:sha1:8cb84c25cb55ac61e423ee39b7dcb6420d302f96 The client times out the context-init counter wait in ~30 s; the previous poll loop spent ~50 s on chan_dump round-trips before injecting. Count the per-channel first-pump log lines straight from dmesg every 0.5 s instead. tools: cuda_cycle.sh polls channels every 2 s to shrink publish latency 2026-09-29T13:45:19+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-09-29T13:45:19+00:00 urn:sha1:497d4d8f333fb750e365e4ff0a32764ed008548b tools: cuda_cycle.sh - one-command CUDA bring-up attempt 2026-09-29T13:29:02+00:00 Arthur Hanson Rasmusson arthur@vgpu.io 2026-09-29T13:29:02+00:00 urn:sha1:6135508cc3b043c35d2e0617870f35b18b29b79c Restart the VM, push the guest tools, start cdt holding on failure, wait for the 20 GR channels, register/pin the completion counters and arm scanerr.py, so each iteration is a single command. scanerr now loops over scanner hits until a hit carries a non-zero RM error record.
